Dear Shanmurray12,
Whispered congratulations on your pregnancy,
If scans are inconclusive, doctors would carry out a series of blood tests to check hCG levels to see if the numbers are rising as expected. However, in isolation, hCG tests only provide a part of the picture - declining levels indicate that a pregnancy has ended and will be miscarried. It can also possibly indicate an ectopic pregnancy that is “self-resolving”. Also hCG levels rising by less than 66% over 48 hours means it is likely (but not certain) that it is ectopic. If levels rise normally, they suggest the pregnancy is implanted in the uterus. You may see from this that hCG levels only indicate certain possibilities and are not in themselves a definitive guide. A positive identification of an implanted embryo on a scan is usually needed before a final diagnosis/certainty that the pregnancy has implanted in the uterus. This is possibly the reason why your doctors are waiting until your appointment to carry out scans.
You have mentioned that your scan showed a small gestation sac a yolk sac but not an embryo, this is known as a Pregnancy of Unknown Location or PUL. This is not a diagnosis but a label until the final location can be identified with certainty. I cannot be sure, but it could be the case that it may be too early to see a pregnancy on the scan.
When I had an early scan with my pregnancy after ectopic pregnancy, I was in exactly the same position as you. I had to wait a week for a repeat scan, and it was such a long wait. I completely understand how you feel and I wish I had words of wisdom to help you pass the time. Try to keep yourself as busy as you can.
I’ll share with you that the next scan I had identified a heartbeat and I went on to have a successful pregnancy, so I hope this gives you some hope.
Sending much love and positive thoughts,
